Though Darwin proposed natural selection as the primary evolutionary mechanism, he accepted other auxiliary mechanisms too. The most important of these was the transmission of acquired characteristics (those acquired by use-disuse) first proposed by Lamarck in the early 1800s..
We now know that the inheritance of acquired characteristics is not an actual mechanism of evolution. Darwin saw that Lamarck had some very good ideas that could lead to evolution. Many of Lamarckâs ideas can be seen in Darwinâs Origin of Species. Lamarck was a believer in immutability. Darwin used this idea to further his research on how species were indeed mutable. Darwin also used Lamarckâs inheritance of acquired characteristics as support for his natural selection idea.
